Abstract

In the present work, employing the conventional reductive perturbation method and the nonlinear eld equations of a plasma consisting of a cold electron uid, hot electrons obeying a non-isothermal (trapped/vortex -like) distribution and station- ary ions with transverse distortion, we studied the propagation of nonlinear waves in such a plasma medium and obtained the modied CKP equation. Seeking a progressive wave solution to this evolution equation we obtained the exact analytical solution. It is observed that the speed of the solitary wave is directional dependent and the wave front is not circularly cylindrical surface any more
